At the risk of becoming increasingly unpopular with the lang folks, for
reasons similiar to those I enumerated in [1] (and others), I'm
uncomfortable with moving Predicate et al to lang. I'm having a lot of
trouble seeing lang as meeting the "Each package must have a clearly
defined purpose, scope, and API -- Do one thing well, and keep your
contracts." criterion.
Don't get me wrong, I think all of this is great stuff, but why does it
all have to be in lang? If it doesn't meet the common reuse principle, it
should be in a different component. The current (i.e., released) contents
of o.a.c.lang, o.a.c.lang.builder, o.a.c.lang.enum and
o.a.c.lang.exception seem reasonably coherent, but I don't think the
either the functor or the reflection packages are a clean fit (with
respect to the CRP, R/REP, etc.), either with each other or the other
classes in lang.
